Avere Systems – is it a cache, is it a tier, does it even matter?

Tier file system with caching, or a cached file system with tiers? Such is the dilemma for Ed Morgan. He took a look at Avere Systems’ Hybrid Cloud overlay for storage backends. With the so-called Tiered File System, Avere is able to increase performance across devices, as well as dynamically move data between mediums based on heat mapping. Hot data lives in RAM, warm data lives on SSDs, and old data is put on nearline NAS, as well as the ability to offload to the cloud. This allows for quick access to frequently used data, while being able to use more efficient storage to hold the bulk of cold data. Ed was impressed by how well this pairs with Avere’s C2N, which serves as the NAS/object storage device that can easily integrate to the public cloud.
